Spring boot 项目打成war包并在idea中运行

1、 修改pom文件原来是jar改成<packaging>war</packaging>

2、 在pom文件中添加移除内置tomcat并且添加添加servlet-api的依赖。

<!--war包部署需要-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <!--&lt;!&ndash; 移除嵌入式tomcat插件 &ndash;&gt;-->
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

3、 启动类修改

public class BootApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
//        SpringApplication.run(BootApplication.class, args);
//        System.out.println("访问地址:localhost");
        SpringApplication application = new SpringApplication(BootApplication.class);
        application.run(args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(BootApplication.class);
    }
}

4、 配置idea的tomcat启动

配置自己本地tomcat

然后在Deployment中找到自己的war

  

运行maven install，如果是部署那么双击package就可以啦。

 

运行就ok啦.
